PS 3:1, 1030 kVA, 220 Vac ou t Safety Precautions 1

1. SAFETY PRECAUTIONS

1.1 Dos Read this manual carefully before operating the UPS.

Review the safety precautions described below to avoid damaging users orequipment.

Install the UPS in a clean and well-ventilated location.

Leave at least 20 cm of clearance space between the ventilation holes of theUPS and other objects or walls.

The UPS must be well grounded to the buildings grounding system with aconductor that has a current carrying capacity that matches the rating of theUPS.

If the unit contains an external battery cabinet, periodically check the groundingconnection between the external cabinet and the main UPS cabinet. (Thebatterys cabinet body must be connected with the grounding screw located on

the rear panel of the electronic cabinet.)

Use the UPS only for its intended purpose.

Allow only qualified technicians to service the UPS. There are no user-serviceable components. Do not try to repair it yourself!

WARNING

Appropriate precautions should be taken during inspection and servicing as

there is a risk of lethal electric shock. (The battery cabinet contains a series of

12-Volt batteries that provide high voltage and energy in the UPS body even

when the UPS is not connected to the electricity mains.)

1.2 Donts Do not open the cover under any circumstances.

Do not insert any objects through the ventilation holes.

Do not put objects on the UPS.

Do not move the UPS while it is operating.

Do not turn the UPS upside down during transportation.

Do not connect or disconnect the cable to the battery cabinet before the battery

circuit breaker is turned off.

Do not turn on the battery circuit breaker when the battery cabinet isdisconnected from the UPS.

WARNING

Do not touch the battery terminals of external batteries with bare hands .

2 General Features PS 3:1, 1030 kVA, 220 Vac ou t

2. GENERAL FEATURES

The PS Series3:1 Phase, Uninterruptible Power Supply (UPS) employs Pulse WidthModulation (PWM) and is controlled by a 16-bit micro-controller, to provide reliable,sophisticated protection for every type of line fluctuation, including interruption of themains (electrical) supply.

Figure 1: UPS Operational Schematic

In case of a power failure, the UPS provides backup power for a specific period of time.

The unit is oriented to operate like module in parallel with similar Gamatronic UPSsystems. The load is shared between the units. The parallel system is the most reliableenergy source for any critical load. If the system uses N+1 UPS units (the redundantparallel system), the output voltage is not interrupted even if one of the units is faulty. Ifthe parallel system is equipped with additional Gamatronic Static Switch unit, the outputvoltage is not interrupted even if more than one UPS is faulty.

The Gamatronic parallel UPS system contains the following features:

Each UPS is equipped with its own battery set

Up to 10 units can be connected in parallel

The system is user-friendly. Its operation is simple and requires no previous technicalknowledge. The UPS operates on-line and once activated, the unit provides voltage of220 V at a stabilized 60 Hz frequency to any practical load.

When backup service is provided (on main line power breakdown), the UPS is poweredby batteries and maintains a constant output voltage supply. The system informs theoperator by means of LED indicators and audible signals of the occurrence of a powerfailure.


7/44


PS 3:1, 1030 kVA, 220 Vac ou t General Features 3

An LCD display on the UPS front panel provides real-time, current operational statusproviding the user with complete information regarding the operational status of theUPS.

Using an RS232 communications port, similar status information may be viewed on acomputer monitor. Additionally, the system may be connected to a remote location viaa modem and a telephone line.

The unit consists of two major subsystems:

Electronic Cabinet, including all electronic devices: charger, inverter, staticswitch, microprocessor board, panel, etc.

Battery Cabinets, including batteries and circuit breaker.

2.1 Major SubsystemsThe device consists of the following modules:

2.1.1 Rectifier/ChargerThe Rectifier/charger supplies stabilized DC voltage to the device at 216 2V

2.1.2 Batteries

The batteries are connected to the charger output and supply voltage during powerfailures. The batteries are housed in the battery cabinets. The UPS include n internal2-pole Battery circuit breaker as shown in figure 1.

2.1.3 Inverter

The inverter receives a DC voltage from the charger or batteries and supplies aregulated, frequency-stabilized, AC voltage (power). The inverter incorporates an IGBTtransistorized bridge; driver, (PC968 board), an L-C filter circuit, isolated outputtransformer circuit, current transformer, PC906 board, and a PC801 control board.

2.1.4 Static Switch

In case the inverter can't supply the load with the correct voltage (i.e. because ofoverload, inrush current on connecting the load, inverter malfunction, etc.), theST.SW/Bypass automatically transfers the load from the inverter to the mains withoutvoltage interruption or disturbance. When the UPS is in BYPASS mode, the load draws

power directly from the mains, bypassing the inverter. The ST.SW automaticallyswitches the load back to the inverter when inverter's output voltage returns to normal.

The inverter is synchronized with the mains in both frequency and phase to ensurecorrect operation of the static switch. The static switch includes PC690/PC920 boardsand RA101 - RA103 contactors.

2.1.5 Control System

The control system performs the following functions:

a. Tests input, bypass, inverter, battery voltage, output current, input/output

signal frequency, and temperature.b. Controls the inverter and the bypass contactorRA101and manages

the static switch and charger voltage during battery tests.


8/44



c. Controls the ALARM interface.

d. Reads the panel keyboard and sends messages to the front panel LCDdisplay.

e. Communicates with devices via the RS232 interface.

The control system includes the PC801 control board, PC075 panel board, PC873power supply, current, and temperature sensors. Measured voltages and currents are

connected to the control board via the PC800 interface board.

2.2 Control PanelThe UPS is equipped with an LCD-display and touch pad control panel that enables theuser to effectively manage the UPS. Once the UPS is installed, the control panelserves as the users primary interface with the system. Messages, warnings and errorconditions are relayed to the user through the control panels LCD display and throughaudible alarms.

Figure 2: Control panel on smaller units (PC074)

Figure 3: Control panel on medium-sized units (PC075)


9/44



Figure 4: Control panel on the larger units (PC085)

2.3 Power On Self TestsThe UPS automatically performs a series of diagnostic tests when initially powered on.

2.4 MeasurementThe user can receive real-time information regarding the units operation and conditionsimply by pressing the appropriate status buttonthe real-time results are displayed onthe front LCD panel. A sample display follows.


10/44



2.5 Real-TimeThe system includes a real-time clock and calendar that sequentially manage the logfile and provides the user with historical data. This information is accessible via theLCD display or, optionally, through the RS-232 communications port.

2.6 CommunicationsThe UPS relays all the measured data and events of the log file through an RS232communications port to a host computer or, using a modem connected to a telephoneline, to a remote location, or via GMAC or GMACi, proprietary SNMP agents, fornetwork access.

2.7 Event LogsThe system compiles a listing of up to 256 extraordinary events of the mains, unit andload during operation. This data is written to the log file and can be accessed easily at

any time through the display panel or computer (optional). This information is veryuseful for maintenance and analyzing performance statistics.

2.8 Ease of UseThe UPS includes an on-line help feature that explains the systems features anddescribes each of the LCD control buttons and indicators.

2.9 Battery CheckThe unit automatically and continuously checks the battery cabinet connection with the

UPS.

2.10 Service ModeThe UPS has a technicians SERVICE MODE that is password protected. Access tothe service mode is only permitted after the technician successfully enters an assignedpassword.

2.11 ConnectionsAll connectionsconnection panel, input, output, and ST. SW are accessed via the

rear panel of the UPS.


11/44



2.12 Parallel Operation (Option)Each UPS can optionally operate in parallel with similar units as part of a modular UPSsystem. Up to 10 units can be connected in parallel.

Special technical solutions are used to synchronize all the units of the system, toprevent circulation of energy between the UPS units and to isolate the faulty unit from

the common power bus. In addition, an active current sharing circuit changes theoutput voltage of each UPS to provide proportional load sharing between the units.

One of the system's units takes on the function of Master. This unit is synchronized tothe mains power. The other units are Slaves and follow the Master. The function ofMaster is not dedicated to one of the units. Any normally functioning UPS can be theMaster.

2.12.1 Centralized vs. Decentralized Static Switch

The UPS employs a Static Switch for functional over-ride. In parallel mode there are 2possible options of Static Switch operation, centralized and decentralized.

In decentralized mode each UPS includes its own Static Switch which worksindependently. However, if one UPS were to fail, the Static Switch would instantly betriggered and supply the load directly from the mains. This would connect the inverterof the other UPS directly to the mains which could potentially damage the other UPS.Therefore, as illustrated below, (Figure 7A) to avoid such a hazard in decentralizedmode, the Static Switches are synchronized using a 3-wire cable.

For additional security, a second option is available as a centralized Static Switch. Asillustrated below, (Figure 7C) there is only one Static Switch (in a separate housing) forthe entire system. This method goes a long way in increasing system reliability,because the output voltage is constant even if both UPSs are disconnected.

PS 3:1, 1030 kVA, 220 Vac ou t Control Panel & Indicators 9

3. CONTROL PANEL & INDICATORS

The control panel serves as an interface between the UPS and the user. Real-timeinformation is displayed visually and audibly. Textual information is presented throughthe LCD display. Messages notifying of alarm conditions are reinforced with an audiblealarm to alert the user of extraordinary circumstances.

The LCD control panel includes function buttonsfor controlling the unit andinformational buttonsfor reporting the status of the UPS.

The console model will be either PC074 (Figure 8), PC075 (Figure 9), or PC085 (. Thetwo consoles have the same functionality; the placement of their buttons and LEDs isslightly different.

In some of the diagrams throughout this user manual only one of the console models isshown, for simplicitys sake.

The control panels of the smaller and medium cabinets (PC074 and PC075) are verysimilar to each other. The control panel of the larger cabinet (PC085) is rather different

in arrangement. Because of this, the PC074 and PC075 panels are explained togetherin section XXXX, and the PC075 panel is described separately in section XXX.
